How it works

Fast probabilistic classifier that assumes features are independent. Often surprisingly accurate for text classification and quick baselines despite the naive assumption.

Use this as a quick baseline classifier or when features are roughly independent.

If features are highly correlated, use Logistic Regression or XGBoost for better results.

Built for: Data scientist, analyst, student

Typical data source: Labeled dataset with binary or multi-class target
